Tech Xplore / How an overlooked electrostatic force could drive the motor of the future
When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges attract each other, drawing objects together. It is natural to think that this attractive force—known ...
Phys.org / Raincoat no longer waterproof? A textile scientist explains why—and how to fix it
You pull on your rain jacket, step out into the storm, and within half an hour your undershirt is soaked. The jacket you purchased as "waterproof" seems to have stopped working, and all the marketing claims feel a bit suspect. ...
Phys.org / Dynamical freezing can protect quantum information for near-cosmic timescales
Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information loss. Physicists have ...
Medical Xpress / Deciding for others can lower confidence in one's own judgments
From the moment we wake to the time we hit the bed at night, we make numerous decisions, some big but mostly small. Although decision-making is a fundamental part of human life, researchers have found that the level of difficulty ...
Phys.org / Beam-spin asymmetry study puts proton models to the test
Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as easy. It requires peeling ...
Phys.org / Simulations show a path to 'ideal glass' with crystal-like entropy
The types of glass that we encounter in everyday life, such as window glass or smartphone screens, are disordered solids. This means that they consist of particles locked in place, like those in solids, but arranged randomly, ...
Phys.org / A fanged frog long thought to be one species is revealing itself to be several
When a new species is discovered, it's tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. "Most people have this image of an intrepid explorer braving an isolated mountain or some other ...
Phys.org / How an underground fungal map of the world's oldest, slowest-growing rainforest trees can boost Earth's resilience
The temperate rainforests of the Chilean Coast Range are home to a spectacular array of life: iridescent blue lizards, tiny wild cats called kodkods, and curly vines of waxy red bellflowers. Towering over this biodiversity ...
Phys.org / Ancient plant-eater with a twisted jaw and sideways-facing teeth was a 'living fossil' in its own time
In a dry riverbed in Brazil, in a dense forest near the Amazon, a team of paleontologists found a fossilized jawbone from an ancient animal. Over the course of their fieldwork, they found eight similar bones, each around ...
Phys.org / Radiocarbon dating rewrites angiosperm trees' lifespan records worldwide
For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many flowering trees—sometimes ...
Medical Xpress / Ultra-processed foods in preschool years associated with behavioral difficulties in childhood
A team led by researchers at the University of Toronto has found an association between ultra-processed foods in early childhood, and behavioral and emotional development. Specifically, the team found that higher ultra-processed ...
Phys.org / Wildlife imaging shows that AI models aren't as smart as we think
Using AI to identify wildlife reveals a potential "transferability crisis," researchers say. Marketing for AI imaging systems often suggests that models can easily tackle novel scenarios across ecosystems and settings, much ...
